Zusammenfassung:A die for use with a cold-formed joint tool such as a clinching tool or clinch punch or self-piercing rivet punch. A split die made of a plurality of partial cup-shaped segments is disposed within a collar that defines a recess. The recess includes a forming area in which the cold-formed joint is formed and a relieved area in which the partial cup-shaped segments are shifted radially outwardly after forming to permit removal of the cold-formed joint tool from the cold-formed joint.
